AD9514BCPZ-REEL7

Clock Buffers, Drivers Overview

The AD9514BCPZ-REEL7 is a low jitter clock distribution IC featuring three independent outputs and programmable dividers. It accepts a differential clock input up to 1.6 GHz. Two LVPECL outputs operate up to 1.6 GHz with additive broadband output jitter of 225 fs rms. The third output supports LVDS (up to 800 MHz, 300 fs rms) or CMOS (up to 250 MHz, 290 fs rms). Each channel includes a divider ranging from 1 to 32 for phase select coarse delay adjustment. The device uses 4-level logic pins for configuration without an external controller and operates on a single 3.3 V supply within the -40°C to +85°C temperature range.

Clock Buffers, Drivers Feature Summary

• Three independent outputs: two LVPECL (1.6 GHz) and one configurable LVDS/CMOS (800 MHz/250 MHz)
• Programmable divide-by factors from 1 to 32 with phase select for coarse delay adjustment
• Low additive broadband output jitter: 225 fs rms (LVPECL), 300 fs rms (LVDS), 290 fs rms (CMOS)
• Hardware configuration via 11 setup pins using 4-level logic; no external controller required

Clock Buffers, Drivers Applications

• Clocking high-speed ADCs, DACs, DDSs, DDCs, DUCs, and MxFEs
• Low jitter, low phase noise clock distribution systems
• High-performance wireless transceivers
• Broadband infrastructure equipment
• Automated test equipment (ATE)

Clock Buffers, Drivers Procurement Notes

Verify package integrity upon receipt, as the component utilizes moisture-sensitive LFCSP packaging. Confirm that the exposed paddle is properly soldered to the PCB ground plane for both electrical connection and thermal dissipation. Ensure the power supply rise time transitions from 2.2 V to 3.1 V within specified limits to guarantee correct output synchronization during power-on.

Clock Buffers, Drivers Selection Notes

Select this component when subpicosecond jitter performance is critical for data converter applications. The AD9514 requires a differential clock input with a slew rate of at least 1 V/ns to meet specifications. Designers must account for the specific voltage levels of the 4-state logic setup pins (VS, GND, 1/3 VS, 2/3 VS) and ensure the RSET resistor value matches the nominal 4.12 kΩ requirement for proper operation.

Clock Buffers, Drivers Part Context

The AD9514BCPZ-REEL7 belongs to the Analog Devices AD9514 series of clock drivers and distributors. The suffix 'BCPZ' indicates the commercial temperature grade (-40°C to +85°C) and lead-free RoHS-compliant construction in a 32-lead LFCSP package. The '-REEL7' designation specifies the tape and reel packaging format for automated surface-mount assembly.
